I'm looking into the purchase of a set of studded Nokian Hakkaetc.. "CS" which look like these except they're not load range E, for my '07 Expedition. The Exp'y doesn't seem to like the "chevron" tread design that its current studded Firestone Winterforce's, and a number of others, offer. The fronts plow in turns, in any measurable snow condition, even at very low speeds. I'm wondering if the more aggressive tread design of the CS's might make a difference.
Even if they're noisier on dry roads, I can live with that, if it keeps me out of the ditch when there's snow!!
